I'm not sure if you have noticed it or not, but most of the time when you click on a text or image that is a link, a fuzzy border appears after you click on it. However on some sites that i've seen, when you click onto the text/image link, the fuzzy border doesn't appear. Is there a code or some sort that can remove it? I find it unattractive.

Within the image tag itself I include style="border:none;". By doing it that way I don't have to worry about style rules on the different states of the a (link, visited, hover, active) or more specific ones like a:link img{} in the stylesheet.
